Using cloud computing techniques to monitor long-term variations in ecohydrological dynamics of small seasonally-flooded wetlands in semi-arid South Africa.
(Journal of Hydrology, 2022)
Wetlands in drylands have high inter- and intra-annual ecohydrological variations that are driven to a great extent by climate variability and anthropogenic influences. The Ramsar Convention on Wetlands encourages the ...
Use of remotely sensed data to estimate tree species diversity as an indicator of biodiversity in BloubergNature Reserve, South Africa
(Taylor and Francis Group, 2022)
We use remotely sensed data to estimate species diversity inBlouberg Nature Reserve (BNR) in the Limpopo province, SouthAfrica to understand the state of biodiversity since communities’involvement in conservation initiatives. ...
Understanding the influence of land cover change and landscape pattern change on evapotranspiration variations in Gwayi catchment of Zimbabwe
(Taylor and Francis Group, 2022)
Understanding dynamics in hydrological processes helps toimprove water resource management. Climate and land coverchanges influence ecohydrological processes. This study soughtto assess the influence of climate, land ...
Mapping rangeland ecosystems vulnerability to Lantana camarainvasion in semi-arid savannahs in South Africa
(Journal of Ecology, 2022)
We mapped and modelled the potential areas vulnerable to Lantana camara (L. camara) invasion in semi-arid savannah ecosystems in the communal lands of Bushbuckridge and Kruger National Park, South Africa. Specifically, we ...
Landuse and landcover change assessment in the Upper Runde sub-catchment, Zimbabwe and possible impacts on reservoir sedimentation
(Physics and Chemistry of the Earth, 2022)
This work assesses land cover changes on the Upper Runde sub-catchment, Zimbabwe, and associated effects on sedimentation rates and risks. The model was implemented using the common Geographic Information Systems tools. ...
Remotely sensed data for estimating chlorophyll-a concentration in wetlands located in the Limpopo Transboundary River Basin, South Africa
(Physics and Chemistry of the Earth, 2022)
Wetlands in semi-arid regions are highly productive and biologically diverse ecosystems that contribute significantly to livelihood and economic development and play a substantial role in sustaining rural livelihoods. These ...
Use of multispectral satellite data to assess impacts of land management practices on wetlands in the Limpopo Transfrontier River Basin, South Africa
(Taylor and Francis Group, 2022)
The study sought to assess the impacts of land use and land cover (LULC) changes on two wetland systems (Makuleke and Nylsvley Nature Reserve) in the Limpopo Transfrontier River Basin (LTRB) in South Africa between 2014 ...
Spectral classification, mapping and physical habitat implications of a riparian invasion by Tamarix ramosissima Ledeb. in the Touws River, Klein Karoo, South Africa
(Taylor and Francis Group, 2022)
This paper investigates the invasion of a reach of the Touws River by the deciduous alien tree Tamarix ramosissima Ledeb. (Pink Tamarisk, Saltcedar). The objectives of the paper were to investigate ...
Use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics along non-perennial rivers in semi-arid environments, South Africa
(Taylor and Francis Group, 2022)
This study explored the use of multi-source remotely sensed data
in monitoring the spatial distribution of pools and pool dynamics
in two distinct semi-arid sites in South Africa. The factors that
control the pool ...
Impacts of the spatial configuration of built-up areas and urban vegetation on land surface temperature using spectral and local spatial autocorrelation indices
(Remote Sensing Letters, 2022)
Understanding how the spatial configuration of land cover patterns of built-up areas and urban vegetation affect urban surface temperatures is crucial for improving the sustainability of cities as well as optimizing urban ...
